the large hooks (Figs 3,11 A,B). On the other hand, total length and basis length of the small hooks for T. "hydatigena" showed a larger value than for T. kotlani (Fig. 2, Fig. 4). Adult specimens have no vaginal sphincter (Fig.7 A). Two measurements (basis length, guard length) were found to be the most important discriminating features for the large hooks among the three species (T. kotlani sp. n., T. hydatigena, T. parenchymatosa) included in the discriminant analysis. On the other hand the total length and the length of the handle contributed to discrimination of the small hooks. Applying discriminant analysis to these measurements gave a correct classification percentage for the three species, which was high (about 90 per cent). Misclassification occurred among 77 hydatigena and T. kotlani for the large hooks and among T. hydatigena and T. parenchymatosa for the small ones (Fig. 5). T. acinonyxi Ortlepp, 1938 Definite hosts are cheetah (Acinonyx jubatus (Schreber, 1775)) and leopard (Panthera pardus (Linnaeus, 1758)). Measurements of the hooks are similar to T. kotlani. Intermediate hosts probably are ungulates, because the hooks recovered from ungulates corresponded to adult hooks and the bladders were similar to the Cysticercus of T. solium and T. ovis. Shape of the non-bifid guard of the adult hooks of T. acinonyxi is different from larval hooks of T. kotlani. T. acinonyxi can also be distinguished from T. kotlani on the basis of the length of the large hooks (see Figs 1,11 C,D). T. acinonyxi has no vaginal sphincter. Measurements of the hooks of the following three taeniids are similar to T. kotlani as well T. hydatigena, and their definitive hosts are big cats and the intermediate host are wild ruminants, too. Fig. 7. Genital organs of two taeniids, A: T. hydatigena (orig. Murai), B: T. hyaenae (after Verster 1969), Scale bar: 0.1 mm Taenia gonyamai Ortlepp, 1938 and T. hlosei Ortlepp, 1938 According to Verster (1969), T. hlosei is synonymous with T. gonyamai Taenia gonyamai was recovered from the lion and T. hlosei Ortlepp, 1938 from the cheetah. The guard is thinner than in species belonging to the above-mentioned taeniids parasitizing Canidae. The vaginal sphincter present. Branches of the uterus of T. gonyamai and T. hlosei are 14 to 22 and 20-30. The number of testes is equal for the A
